Marinco 103RN 20A/30A Weatherproof Cover

Marinco 20A/30A Weatherproof Cover with Threaded Sealing Ring (103RN)

The Marinco 103RN is a heavy-duty marine protective boot and cover designed to protect 20 Amp and 30 Amp marine shore power female connectors (such as Marinco 305CRN and 205CRN) from moisture, salt spray, dirt, and UV degradation.

Molded from high-flexibility, UV-stabilized marine vinyl, the boot features an integrated heavy-duty threaded sealing ring. When screwed onto a mating shore power inlet (or male plug boot), the sealing ring creates a watertight barrier that prevents environmental moisture and spray from wicking into the electrical contact terminals.
